I have a general question, how likely is it that the same person would have two entries in a census record? I ask because in the 1841 census for Dunfermline there are only two James Stewarts of 30 years old. One is living with his wife Elizabeth and sons James and Robert (my ancestor). The other is living with his parents William and Janet Stewart. Both are described as linen weavers. In the 1851 census, there are no 40 year old James Stewarts living in Dunfermline, only 1 in Fife (and he is not either the two in dispute here). Across Scotland, there are 76 other James Stewarts of the right age, none of them born in Fife/Dunfermline and the only ones described as weavers are not the right ones. So, both of the James Stewarts of 30 years old in 1841 have disappeared by 1851. Bit of a coincidence, could we be talking about the same man? A likely scenario would be, on the night of the census he was visiting his parents, so his dad filled him in as being at the parental home. But as the head of his own family he had to provide their details for his house and included himself too. Does this sound likely?
